I'm glad you found the two Updike poems interesting, and liked them as well. A truly brilliant book by Updike is titled "Gertrude and Claudius." In a way, this is his "Hamlet piece," just as Tom Stoppard's "Rosencrantz and Guildenstern Are Dead," was. When I taught "Hamlet" at Bronx Science, I had them read R&G first. They loved it. There's part where Claudius asks one of the guys "Is Hamlet crazy?" (in effect) and I passed the question to the class. One fellow, a gymnast, pointed his foot to the ceiling, and said "No, he's stark raving sane." I never had a bad class.
